Wearable device with gesture recognition module

ABSTRACT

A system includes a wearable device including a gesture recognition module configured to detect a gesture using the gesture recognition module. A wireless device is configured to implement one or more functionality types. The wearable device can wirelessly detect the wireless device and obtain a code from the wireless device. The wearable device detects a gesture and in response, transmits the code to the wireless device to cause the wireless device to implement at least one of the one or more functionality types.

BACKGROUND

Many types of devices require a user to physically engage the device insome manner in order to induce a state change in the device. Forexample, a lock on a secured door or cabinet can utilize a securitydevice to unlock the secured door or cabinet. For example, a user maywear a security badge that communicates with the security device toallow access to and unlock the secured door or cabinet. Typically, theuser may swipe the security badge proximate a badge reader to unlock thedoor. However, this technique to unlock the secured door or cabinetrequires the user to perform additional inconvenient motions with thesecurity badge. For example, if the user is not wearing the securitybadge, they may have to physically search their pockets or retrieve thesecurity badge from their wallet. Then, the user must physically placethe security badge in proximity of the badge reader. This can takeadditional time and, if the user is in a hurry, can slow the user down.Other types of devices require the same, similar or additional physicalengagement to induce a state change in the device.

DETAILED DESCRIPTION Overview

Various embodiments provide a wireless device that implements one ormore functionality types, a wearable device including an RFID device,and a gesture recognition module that work together to implement thefunctionality or functionality types. Specifically, in at least someembodiments, the wearable device is configured to wirelessly detect thewireless device and obtain a code from the wireless device. The code isconfigured to be used to cause or otherwise induce a state change in thewireless device. Specifically, the wearable device is configured todetect a gesture using the gesture recognition module and, responsive todetecting the gesture, transmit the code via the RFID device effectiveto cause the wireless device to implement at least one of thefunctionality types, e.g., to cause the above-mentioned state change.The gesture is associated with the functionality type such that when thegesture is detected, the code is transmitted to induce the state changein the wireless device. This can relieve the user of having tophysically engage the wireless device in order to change a stateassociated with the wireless device. Such a state change can pertain toany state change associated with the wireless device, such as anoperational state.

In some embodiments, the wireless device is a secured object, such as adoor, cabinet, or other lockable device that incorporates a securitydevice, such as a lock, that allows or denies access to the securedobject. A wearable device is configured to be worn by a user and canreceive, via a wireless transceiver, an unlock passcode from the lock—inthis case, a wireless lock device. The wearable device may then detectan unlock gesture performed by a user wearing the wearable device, andresponsive to detecting the unlock gesture, transmit the unlock passcodeto the wireless device to unlock the wireless device. So, in thisinstance, the functionality type pertains to locking/unlocking awireless lock device, and the corresponding state change is one oftransitioning from a locked state to an unlocked state, or from anunlocked state to a locked state. As noted above, this can, but need notnecessarily, relieve the user of having to physically engage thewireless device in order to change a state associated with the wirelessdevice.

While features and concepts of wirelessly-induced state change usinggestures can be implemented in any number of different devices, systems,environments, and/or configurations, embodiments of wirelessly-inducedstate change using gestures are described in the context of thefollowing example devices, systems, and methods.

Example Operating Environment

FIG. 1 illustrates an example operating environment 100 in whichembodiments for wirelessly-induced state change using gestures can beimplemented. The example environment 100 includes a wearable device 102and a wireless device 104. The wearable device 102 may be any type ofdevice that includes sensors 106 that can be used for detecting motion.In this example, the wearable device 102 includes a gesture recognitionmodule 108, which represents functionality that enables communicationwith the sensors 106 to detect whether a particular gesture is performedby a user wearing the wearing device, as further described herein. Thesensors 106 can include, by way of example and not limitation, anaccelerometer(s), gyroscope(s), force sensor(s), heat sensor(s), and anyother sensor that can or might be used for gesture recognition. Fordiscussion purposes, gesture recognition module 108 is illustrated as asingle module, but it is to be appreciated that gesture recognitionmodule 108 can be implemented using any suitable combination ofhardware, software, and/or firmware. The wearable device 102 can also beimplemented with additional, various components, such as a processingsystem and memory (not shown), and any number and combination ofcomponents as further described with reference to the example deviceshown in FIG. 6.

In this example environment 100, the wearable device 102 also includesone or more transceivers 110 that enable the wearable device 102 towirelessly communicate 112 with the wireless device 104, as describedbelow in more detail. The transceivers 110 can employ any suitable typeof technology to enable communication with wireless device 104including, by way of example and not limitation, Bluetooth, Wi-Fi,radio-frequency identification (RFID), cellular, near fieldcommunication (NFC), and the like.

The wireless device 104 includes, among other components, a code 114,such as an access code, and one or more transceivers 116. The code 114can be saved on some type of computer-readable storage medium and usedby the wireless device 104 to provide to the wearable device 102 toinitiate various functionality that is performed by the wireless device104 or a device communicatively coupled to the wireless device 104. Thatis, the code 114 can be transmitted from the wireless device 104 to thewearable device 102 and, once the gesture recognition module recognizesa particular gesture, the code 114 can be re-transmitted from thewearable device 102 to the wireless device 104 to serve as anauthentication or verification that a functionality associated with thatparticular gesture and code is to be performed by the wireless device.The wireless device 104 can also be implemented with additional, variouscomponents, such as a processing system and memory (not shown), and anynumber and combination of components as further described with referenceto the example device shown in FIG. 6.

As mentioned above, the transceivers 116 enable the wireless device 104to wirelessly communicate 112 the code 114 to the wearable device 102.The transceivers 116 can employ any suitable type of technology toenable communication with the wearable device 102 including, by way ofexample and not limitation, Bluetooth, Wi-Fi, RFID, cellular, NFC, andthe like.

In implementations, the wearable device 102 receives the code 114 fromthe wireless device 104 and stores the code 114 in memory, as describedbelow in more detail. The code is associated with or otherwise “mapped”to a particular gesture and a functionality associated with the gesturethat can be performed by the wireless device. When the gesturerecognition module 108 detects the particular gesture performed by theuser of the wearable device 102, the code 114 is transmitted orre-transmitted from the wearable device 102 back to the wireless device104. By receiving the code 114 back from the wearable device 102, thewireless device now knows that it can perform the functionality that isassociated with the code and the gesture.

In another example, the environment 100 includes a mobile device (notshown), the wearable device 102, and the wireless device 104. The mobiledevice may be any type of device that includes transceivers that can beused to communicate with the wearable device 102 and the wireless device104. The transceivers of the mobile device can employ any suitable typeof technology to enable communication with wireless device 104including, by way of example and not limitation, Bluetooth, Wi-Fi,radio-frequency identification (RFID), cellular, near fieldcommunication (NFC), and the like. The mobile device can also beimplemented with additional, various components, such as a processingsystem and memory (not shown), and any number and combination ofcomponents as further described with reference to the example deviceshown in FIG. 6.

The mobile device and the wearable device 102 can operate together tofacilitate wirelessly-induced state change using gestures. Inimplementations, the mobile device receives the code 114 from thewireless device 104 and stores the code 114 in memory. When the gesturerecognition module 108 of the wearable device 102 detects the particulargesture performed by the user of the wearable device 102, the mobiledevice receives an indication from the wearable device 102 that theparticular gesture was performed and, in response to the indication, thecode 114 is transmitted or re-transmitted from the mobile device back tothe wireless device 104. By receiving the code 114 back from mobiledevice, the wireless device 104 can perform the functionality that isassociated with the code and the gesture.

Having considered an example operating environment, consider now anexample wearable device in accordance with one or more embodiments.

Example Wearable Device

FIG. 2 illustrates an expanded view of the wearable device 102 ofFIG. 1. The wearable device 102 includes processor(s) 202 andcomputer-readable media 204. Applications and/or an operating system(not shown) embodied as computer-readable instructions oncomputer-readable media 204 can be executed by processor(s) 202 toprovide some or all of the functionalities described herein. Tofacilitate wirelessly-induced state change using gestures, wearabledevice 102 includes gesture recognition module 108 and control module206. Here, gesture recognition module 108 and control module 206 arestored on computer-readable media 204. However, while gesturerecognition module 108 and control module 206 are illustrated here asresiding on computer-readable media 204, the gesture recognition module108 and the control module 206 can alternately or additionally beimplemented using hardware, firmware, or any combination thereof.

As noted above, the gesture recognition module 108 representsfunctionality that enables communication with the sensors 106 to detectwhether a particular gesture is performed by a user wearing the wearingdevice. So, for example, sensors 106 may sense motion of the user, andthe motion may have a profile that is associated with a gesture. Themotion may, for example, be characterized by movement in a firstdirection, followed by movement in a second direction, followed by yetanother movement in a third different direction. These three movementscan be sensed by the sensors 106 and then identified by the gesturerecognition module 108 to be associated with a particular gesture.

The control module 206 represents functionality that enables control ofthe device components of the wearable device 102. For example, thecontrol module 206 can be implemented to receive an indication from thegesture recognition module 108 that a particular gesture is performed bya user of the wearable device 102. The control module 206 can thendirect the transceivers 110 to transmit security information 208, e.g.,code 114, or other information stored in the computer-readable media 204to a corresponding wireless device.

The control module 206 can also be implemented to obtain informationfrom the wireless device. For example, the control module 204 can obtaininformation stored in wireless device 104 via transceivers 110. Theinformation received is then stored on computer-readable media 204 andcan be utilized by the gesture recognition module 108 and/or controlmodule 206 as described above and below.

The security information 208 can include information or data associatedwith the wearable device 102 and/or the wireless device 104. Continuingwith the example discussed above, the code 114 stored by wireless device104 is transmitted to the wearable device 102, and stored or maintainedas security information 208. Additionally, the security information 208can include information associated with communicating with the wirelessdevice 104, such as pairing information of the wearable device 102 andthe wireless device 104, public/private encryption keys, usercredentials, and the like.

The wearable device 102 also includes a power source 210, such as abattery, to power the various device components of the wearable device102.

Having considered an example wearable device, consider now examplegestures in an operating environment in accordance with one or moreembodiments.

Example Gestures in an Operating Environment

FIGS. 3a and 3b illustrate an example operating environment 300 in whichembodiments for wirelessly-induced state change using gestures can beimplemented. The example environment 300 includes a wearable device 102(shown as a wristband) and the wireless device 104 from FIG. 1.

Consider FIG. 3a , which illustrates the wearable device 102 approachingthe wireless device 104. The wearable device 102 is at a distance D1away from the wireless device 104 such that the distance D1 is within acommunication range 304 of the transceivers of both devices. Thedistance D1 is a first threshold distance for the wireless device 104 tocommunicate a code (e.g., code 114) to the wearable device 102. Forexample, the wearable device 102 and the wireless device 104 can eachimplement a Bluetooth transceiver that typically has a communicationrange of approximately 10 meters. When the wearable device 102 is withinBluetooth communication range, the wireless device 104 transmits thecode 114 to the wearable device 102 via the Bluetooth transceiver.Additionally, the wireless device 104 can transmit additionalinformation stored in memory of the wireless device 104 to the wearabledevice 102 when the code 114 is transmitted via Bluetooth.Alternatively, the wearable device 102 can transmit a request to thewireless device 104 to obtain the additional information via Bluetooth.

Alternatively, when the wearable device 102 is at or within the distanceD1 away from the wireless device 104, the wireless device 104 canexecute a pairing method to pair the devices for communication.Continuing with the example above, the wireless device 104 may determinethat the wearable device 102 has not been previously paired viaBluetooth and can execute a pairing method to pair the devices. Thepairing of the devices can be implemented using any suitable Bluetoothpairing method.

In FIG. 3b , the wearable device 102 is now at a distance D2 away fromthe wireless device 104 such that the distance D2 is within a differentcommunication range. The communication range may or may not be oneassociated with another one of the transceivers of both devices. Thedistance D2 is a second threshold distance for the wearable device 102to communicate the code back to the wireless device 104, where thedistance D2 is less than the distance D1. For example, the wearabledevice 102 may include a passive RFID tag and the wireless device 104may include an RFID reader. The RFID reader of the wireless device 104is implemented to communicate with the RFID tag of the wearable device102 via inductive coupling, typically having a communication range ofapproximately one meter. The inductive coupling allows the RFID readerof the wireless device 104 to power and communicate with the RFID tag ofthe wearable device 102.

Alternatively, the same type of transceiver can be implemented tocommunicate at the distance D1 and the distance D2. For example,Bluetooth transceivers can be implemented by each device to communicateat the distance D1 and the distance D2, or RFID transceivers can beimplemented by each device to communicate at the distance D1 and thedistance D2.

In one or more embodiments, after receiving the code from the wirelessdevice 104, the user may execute a gesture and the wearable device 102may determine that the particular gesture has been performed. Forexample, the wearable device 102 can determine that the user performed aclockwise twisting gesture 310 and a counter-clockwise gesture 312 viathe sensors 106, while the wearable device 102 is within the distanceD2. Responsive to determining that the user has performed the gesture,the wearable device 102 can then communicate the code received from thewireless device 104 back to the wireless device 104 via the RFID tag.The wireless device 104 receives the code from the wearable device 102and, responsively, performs one or more functions associated with thecode on either the wireless device 104 or a device communicativelycoupled to the wireless device 104.

It should be noted that the wearable device can be a device embeddedinto an article of clothing, such as a sleeve or cuff of a shirt orjacket, rather than a wristband as described above. In another example,a mobile device (not shown) can be utilized with a wearable deviceembedded in an article of clothing for wirelessly-induced state changeusing gestures. In one or more embodiments, the mobile device and thewireless device 104 can each implement a Bluetooth transceiver, and whenthe mobile device is at the distance D1 away from the wireless device104, the wireless device 104 communicates the code to the mobile devicevia the Bluetooth transceiver. Additionally, the wireless device 104 cantransmit additional information stored in memory of the wireless deviceto the mobile device when the code is transmitted. Alternatively, themobile device can transmit a request to the wireless device 104 toobtain the additional information.

In one or more embodiments, the wearable device may include a passiveRFID tag, and the mobile device and the wireless device 104 may eachinclude an RFID reader. The RFID reader of the mobile device isimplemented to communicate with the RFID tag of the wearable device andcommunicate with the RFID reader of the wireless device 104.

When the mobile device and the wearable device are at the distance D2away from the wireless device 104, the user may execute the gesture andthe wearable device may determine that the particular gesture has beenperformed. The wearable device can then communicate an indication to themobile device that the user has performed the gesture via the RFID tag.Responsive to receiving the indication, the mobile device can thencommunicate the code received from the wireless device 104 back to thewireless device 104 via the RFID reader. The wireless device 104receives the code from the mobile device and, responsively, performs oneor more functions associated with the code on either the wireless device104 or a device communicatively coupled to the wireless device 104.

As noted above, the wireless device 104 can be any suitable type ofwireless device. In one or more implementations, the wireless device 104is a door lock that unlocks or locks based on the gesture performed bythe user. One such wireless device in the form of a door lock is shownin FIG. 4.

There, an example door lock 400 includes processor(s) 402 andcomputer-readable media 404. Applications and/or an operating system(not shown) embodied as computer-readable instructions oncomputer-readable media 404 can be executed by processor(s) 402 toprovide some or all of the functionalities described herein. Tofacilitate wirelessly-induced state change using gestures, thecomputer-readable media 404 of the door lock 400 includes state changemodule 406 and security module 408. Here, state change module 406 andsecurity module 408 are stored on computer-readable media 404. However,while state change module 406 and security module 408 are illustratedhere as residing on computer-readable media 404, state change module 406and security module 408 can alternately or additionally be implementedusing hardware, firmware, or any combination thereof.

In one or more embodiments, the security module 408 representsfunctionality that generates and/or otherwise stores codes or passcodesin computer-readable media 404. Alternatively, the state change module406 or another module (not shown) can be implemented to generate thecode 114. The security module 408 can also be implemented to generate anew code after each use of the code 114. For example, after the securitymodule 408 validates a received code from the wearable device, thesecurity module 408 may generate a new code to unlock/lock the door lock400 and store the new code as code 114.

In one or more embodiments, the security module 408 can be implementedto generate multiple different codes, where each code corresponds to aparticular functionality of the door lock 400. For example, the securitymodule 408 generates an unlock code and a lock code that are transmittedto the wearable device. If a user of the wearable device performs agesture associated with the unlock functionality of the door lock 400(e.g., FIG. 3 element 310), then the door lock 400 receives the unlockcode from the wearable device. Likewise, if the user of the wearabledevice performs another gesture associated with the lock functionalityof the door lock 400 (e.g., FIG. 3 element 312), then the door lock 400receives the lock code from the wearable device. Additionally,responsive to receiving the unlock code or the lock code from thewearable device, the security module 408 generates and stores anewunlock code or a new lock code.

In one or more embodiments, the security module 408 can also beimplemented to execute a pairing method to pair the door lock 400 todevices for communication. For example, the security module 408generates encryption keys to enable secure communication between thedoor lock 400 and the wearable device 102. The encryption keys includepublic/private keys or any suitable encryption keys conforming to aparticular wireless specification (e.g., Bluetooth specification v1.1 ornewer). Alternatively, one of the transceivers 420 generates theencryption keys to enable secure communication between the door lock 400and the wearable device 102, and the security module 408 obtains theencryption keys from the one transceiver to store in computer-readablemedia 404.

The state change module 406 can be implemented to store information inthe computer-readable media 404 as device information 410. For example,the state change module 406 is communicatively coupled to lock mechanism412 of the door lock 400 and can store information indicating a statusof the lock mechanism 412 as lock state 414. The lock state 414indicates whether the lock mechanism 412 of the door lock 400 is lockedor unlocked. For example, the door lock 400 receives and authenticatesthe code 114 from the wearable device, and based on the lock state 414that indicates the lock mechanism 412 is locked, the state change moduledirects the lock mechanism 412 to unlock and updates the lock state 414.Alternatively, if the current lock state 414 indicates that the lockmechanism 412 is unlocked, then the state change module directs the lockmechanism 412 to lock in response to receiving and authenticating thecode 114 from the wearable device.

The device information 410 can also include a handle type 416 thatindicates a type of handle associated with handle 418 of the door lock400. It should be noted that the handle 418 and the locked mechanism 412are separated in function. For example, if the lock mechanism 412 islocked, and a user tries to open the door using the handle 418, then thedoor does not open even though the user is able to turn the handle 418.The function of the door unlocking is controlled by the lock mechanism412 of the door lock 400.

As illustrated, the handle 418 is a lever type handle that requires adownward clockwise rotation to open the door. Other types of handles forthe door lock 400 can be implemented. For example, rather than thehandle 418 being a lever type handle as illustrated, the handle 418 canbe a knob type handle and the handle type 416 indicates that the handle418 is a knob type handle. In another example, the door lock 400 isimplemented on a powered sliding door that has no handle, and the handletype can indicate that the door lock 400 has no handle.

The lock state 414 and/or handle type 416 can be provided to thewearable device. For example, the door lock 400 transmits the code 114along with the lock state 414 and/or handle type 416 via transceivers420 to the wearable device 102 via Bluetooth when the wearable device102 is within Bluetooth communication range (e.g., distance D1) of thedoor lock 400. Alternatively, lock state 414 and/or the handle type 416can be transmitted to the wearable device during the pairing processbetween the wearable device and the door lock 400, or as an additionalcommunication transaction.

In one or more embodiments, the wearable device 102 can be implementedto utilize the information received from the door lock 400 as a basis todetermine which gestures performed by a user of the wearable device 102cause the wearable device 102 to transmit the code 114 back to the doorlock 400. In other words, a particular gesture performed by the useracts as a trigger event for the wearable device 102 to transmit the code114 to the door lock 400. For example, the information received from thedoor lock 400 may indicate that the handle type 416 associated with thedoor lock 400 is a lever. This information can be mapped to a gesturetype that is associated with unlocking the door. That is, the wearabledevice 102 can utilize the handle type 416 as a basis for determining aparticular gesture that causes the wearable device 102 to transmit thecode 114 back to the wireless device 102 to unlock the door lock. Inthis particular example, the wearable device 102 may determine that adownward rotating motion is a typical motion to open a door with a leverhandle. When a user of the wearable device 102 performs the downwardrotating motion, the wearable device 102 detects the downward rotatingmotion and, as a result, transmits the code 114 back to the door lock400 to unlock the door lock. The door lock 400 verifies the codereceived from the wearable device 102 against the generated and/orstored code. If the code received is validated and matches, then thedoor lock 400 unlocks the door. If the code is not validated, then thedoor lock 400 remains locked. Thus, the user can, in many instances,cause the door to be unlocked before they are in physical contact withthe door.

In another example, the information received from the door lock 400 mayindicate that the handle type 416 associated with the door lock is aknob. The wearable device 102 may then determine that a twisting motionis the typical motion to open a door with a knob handle. When a user ofthe wearable device 102 performs the twisting motion, the wearabledevice 102 detects the twisting motion and transmits the code 114 backto the door lock 400 to unlock the door lock.

In yet another example, the door lock 400 might be implemented on asliding door and the information received from the door lock indicatesthat a handle type associated with the door lock is a sliding doorhandle or no handle at all. The wearable device 102 may then determinethat a horizontal swipe motion of the user's hand will cause the code114 to be transmitted to the door lock 400. When a user of the wearabledevice 102 performs the horizontal swipe motion, the wearable device 102detects the horizontal swipe motion and transmits the code 114 back tothe door lock 400 to unlock the door lock.

In one or more embodiments, the user can physically interact with thehandle 418 of the door lock 400 and perform a motion on the handle thatwould typically open the door if the door was not locked. The wearabledevice 102 can detect this motion on the handle, and can determine thatthe motion performed by the user is the gesture to unlock the door lock.Hence, the gesture can be employed to unlock the door when the userphysical interacts with the door handle. Alternatively, the user canperform the same gesture in the air without any interaction with thehandle, and the wearable device 102 can detect the same motion and causethe door to be unlocked.

In implementations, the door lock 400 may be configured to open or closea door. The door lock 400 can be communicatively coupled to a devicethat controls opening and closing the door. For example, after unlockingthe door lock in response to receiving a valid code from the wearabledevice 102, the door lock can communicate with the device that controlsthe door to open the door.

As noted above, the wireless device can comprise any suitable type ofwireless device that can perform a functionality responsive to receive are-transmitted code from a wearable device. For example, the wirelessdevice 104 may be an ignition device of a vehicle that starts or stopsthe engine of the vehicle. The ignition device can generate and/or storea code in memory that can be utilized by the wearable device 102 tostart/stop the vehicle. Additionally, the ignition device can storeinformation in memory that includes an ignition state and an ignitiontype associated with the ignition device. For example, the ignitiondevice can communicate the code and/or information to the wearabledevice 102 via Bluetooth when the wearable device 102 is withinBluetooth communication range (e.g., distance D1) of the ignitiondevice. The wearable device 102 can utilize the information receivedfrom the ignition device as a basis for determining which gesturesperformed by the user of the wearable device 102 causes the wearabledevice 102 to transmit the code back to the ignition device. As thewearable device 102 moves closer to the ignition device, the user canperform a clockwise twisting gesture 310 or another suitable gesturewhile the wearable device 102 is within RFID communication range (e.g.,distance D2). The wearable device 102 can determine that the gestureperformed by the user is an appropriate gesture to start the vehiclebased on the information received from the ignition device. In responseto the user performing the clockwise twisting gesture 310, the wearabledevice 102 can transmit the code back to the ignition device to startthe vehicle. The ignition device can verify the code received from thewearable device 102 against the generated/stored code. If the codereceived is validated and matches, then the ignition device can startthe vehicle. If the code is not validated, then the ignition device doesnot start the vehicle.

Having considered an example gestures and operating environments inaccordance with one or more embodiments, consider now an examplewireless device that can be employed in connection with theabove-described embodiments.

Example Techniques for Wirelessly-Induced State Change Using Gestures

FIG. 5 illustrates an example method 500 of wirelessly-induced statechange using gestures in accordance with one or more embodiments.Generally, any services, components, modules, methods, and/or operationsdescribed herein can be implemented using software, firmware, hardware(e.g., fixed logic circuitry), manual processing, or any combinationthereof. Some operations of the example methods may be described in thegeneral context of executable instructions stored on computer-readablestorage memory that is local and/or remote to a computer processingsystem, and implementations can include software applications, programs,functions, and the like. Alternatively or in addition, any of thefunctionality described herein can be performed, at least in part, byone or more hardware logic components, such as, and without limitation,Field-programmable Gate Arrays (FPGAs), Application-specific IntegratedCircuits (ASICs), Application-specific Standard Products (ASSPs),System-on-a-chip systems (SoCs), Complex Programmable Logic Devices(CPLDs), and the like. The order in which the method is described is notintended to be construed as a limitation, and any number or combinationof the described method operations can be performed in any order toperform a method, or an alternate method. In the illustrated diagram,operations that are performed by a wearable device are designated“wearable device” and operations that are performed by a wireless deviceare designated “wireless device”.

The operations assume that a user is wearing a wearable device, such asthat described above. At 504, a determination is made by the wearabledevice as to whether a wireless device, such as wireless device 104(above) is detected. The wireless device 104 can be detected in anysuitable way. For example, various different technologies can beemployed to detect the wireless device 104 including, by way of exampleand not limitation, Bluetooth, Wi-Fi, RFID, cellular, NFC, and the like.If the wireless device 104 is not detected (i.e. the “No” branch), theoperations return to 504 and the wearable device continues scanning fora wireless device. In an alternative example, at 504, a mobile devicecommunicatively coupled to the wearable device determines whether thewireless device is detected.

When a wireless device is detected at 504 (i.e., the “Yes” branch from504), then at 506, a determination is made by the wireless device as towhether a trust relationship exists with the wearable device or whetherthe devices have been previously paired. If the wearable device is nottrusted (i.e., the “No” branch from 506), then at 508, the wirelessdevice executes a method to pair the devices. The pairing can include asecure key exchange between the devices to allow for securecommunication (e.g., encrypted communication) between the devices. So,in this instance, the wireless device and the wearable device mayexchange public keys so that transmissions from each device that areencrypted with the other's public key, can only be decrypted with theother's corresponding private key. At 510, the wearable device 102 pairswith the wireless device 104 or otherwise establishes a trustrelationship. Continuing with the alternative example above, at 506, adetermination is made by the wireless device as to whether a trustrelationship exists with the mobile device or whether the devices havebeen previously paired. The wireless device and the mobile device mayexchange public keys so that transmissions from each device that areencrypted with the other's public key, can only be decrypted with theother's corresponding private key. At 510, the mobile device pairs withthe wireless device 104 or otherwise establishes a trust relationship.

If the wearable device is trusted (i.e., the “Yes” branch from 506) orafter the pairing of the wearable device and the wireless device at 510,then at 512, a code (e.g., code 114) is transmitted from the wirelessdevice to the wearable device. For example, code 114 transmitted fromthe wireless device to the wearable device is stored on the wearabledevice as security information 208. Continuing with the alternativeexample above, if the mobile device is trusted or after the pairing ofthe mobile device and the wireless device, then at 512, a code (e.g.,code 114) is transmitted from the wireless device to the mobile device.

At 514, after the code has been received or otherwise stored, adetermination is made as to whether a gesture is performed. The gesturebeing performed can be determined in any suitable way. For example,various different technologies (i.e. sensors) can be employed to detectmotion, position, acceleration, directional changes, and the like, ofthe wearable device including, by way of example and not limitation, anaccelerometer, a gyroscope, and the like.

If the gesture is not performed by the user of the wearable device(i.e., the “No” branch from 514), the wearable device continues todetermine whether the gesture is performed by the user or simply waitsfor the gesture to be performed. Although, not illustrated, there may bea condition in which the wearable device loops through the process at514 and the user moves outside of the detection range of the wirelessdevice. To resolve this condition, the method can be implemented torestart at 504.

If the gesture is performed (i.e., the “Yes” branch from 514), then at516, the wearable device 102 transmits the code received at 512 back tothe wireless device. Continuing with the alternative example above, ifthe gesture is performed, then at 516, the wearable device 102 transmitsan indication to the mobile device that the gesture is performed. Themobile device then transmits the code back to the wireless device inresponse to the indication from the wearable device.

At 518, the wireless device receives the re-transmitted code and, inresponse to receiving the code, performs one or more functions. Thewireless device can be implemented to perform one or more functionsassociated with the wireless device itself, or associated with a devicethat is communicatively coupled to the wireless device.

Having considered an example method in accordance with one or moreembodiments, consider now example gestures and operating environmentthat can be employed in connection with the above-described embodiments.
